- DINNER-FAIL.

SFECIEIGATION forming part of Letters Patent No. 543,327, dated July 23, 1895.

Application iled October 1, 1894. Serial No. 524,672. (No model.)

T all whom 1315 may concern:

Be it known that I, CHARLEsELMAR BER- TELS, acitizen of the United States, residing at Wilkes-Barr, in the county of Luzerne and State of Pennsylvania,have ,invented certain 'new and useful Improvementsv in Dinner- Fails, of which the followingis a specification. My invention relates-to dinner-pails, and more particularly to suchv pails as have a,

holder for coffee or other liquid surmounted by a collar or pouring-tube, upon which the drinking-cup is usually placed for convenience orto serve as a cap or closure.

It frequently happens that a dinner-pail is upset andthe liquid contents spilled because of the accidental removal of the cup. It is the zlo purpose of my invention to prevent accidents of this class, and to this end the invention consistsin forming the pouring-tube or collar of the can with a locking crease or thread, preferably spiral, and in forming upon the cup a crease or spiral thread which will interlock with the collar. `The main portion of the side of the cup is plain, the crease or thread occupying but a small percentage of the surface and thereby avoiding any difficulty in keeping the cup clean, and the plain annularA side view of a dinner-pail havingits upper portion broken away to show the liquid-holder. Fig. 2 is a sectional view of one form of collar and cup, and Fig. 3 is a similar sectional view of another form of the invention.

Referring particularly to Figs. 1 and 2, A

indicates a liquid-holder which fits upon and forms a cover for the pail B. The holder A isprovided with the usual collar or pouringspout D, which is preferably of the same diameter as the drinking-cup. In these iigures the cup E is enlarged at the bottom and reduced at the top, there being an offset or shoulder e about midway of its height. Above the offset e are formed one or more spiral creases or threads e whichv interlock with corresponding threads d impressed in the collar D. The enlarged lower part c2 of the cup and the reduced upper part e8 are plain, and it is therefore an easy matter to keep the cup clean. The enlarged lower part e2 serves asa handle to unfasten the cup and also increases its capacity. To strengthen the upper edge of the cup itis turned inward and rounded, as shown at e4. This also produces a smooth well-finished edge which is agreeable to drink from, while at the same time it does not interfere with the insertion of the cup into the spout or collar. The upper edge of the collar is curled outward, as shown at d', and the should-er c fits tightly down upon this edge, thus forming what is practically a steam-tight joint, which, together with the closelytting screw-joint, not only prevents the spilling of the inclosed fluid, but prevents the escape of steam and therefore keeps it from cooling rapidly.

In Fig. 3 I have shown a cup which, in general outline, is the same as that shown in Fig. 2. lt is provided with a shoulder e and an inwardly-curled edge e4, but the locking device consists of a bayonet-joint instead of a screw-joint. As shown, the cup has two or more inwardly-pressed creases F, each having a vertical branch f, extending downward from the edge of thecup, and an inclined or spiral branch f', which is equivalent to the spiral threads of the cup shown in Fig. 2. Thecollar D is provided with a curled upper edge d t similar to that shown in Fig. 2, and with two or more inwardly-pressed points d2 adapted to engage with the grooves or depressions F.

The manner of locking the cup shown in Fig. 3 to the collar will be evident from the above description and the drawings. The cup is placed in the collar with the vertical groovesfin line with the points d2, and then pressed down until the points reach the inclined grooves f. The cup is then turned until the shoulder e engages the curled upper edge d of the collar, thereby lookin g the cup and closing the liquid-holder tight.

Having described my invention, what I claim isl. As an improved article of manufacture, a liquid holder having a collar or neck `with means for engaging a cup, a plain annular space above said means, and a flange or shoulder, in combination with a shouldered cup provided with an enlarged lower part and tted inside of the collar or neck with corresponding means for engaging the latter and a plain annular surface which is in close contact with the collar when the same is closed, substantially as and for the purposes described.

2. As an improved article of manufacture, a liquid holder having a collar or neck with locking means for securing a cup, a plain annular space above said means, and a flange or shoulder, in combination with a cup having a shoulder and an enlarged lower portion, fitted inside of the collar or neck, with corresponding means to engage the latter and a plain annular surface which is in close contact with the collar when the same is closed, substantially as and for the purposes described.

3. As an improved article of manufacture, a liquid holder having a collar or neck with a threaded portion and a plain annular surface above the same, in combination with a is screwed home, substantially as and for the A purposes described.
